Abstract

Die vorliegende Erfindung betrifft eine Filtervorrichtung zum Stoffaustausch zwischen zwei durch eine Membran getrennten Medien.The present invention relates to a filter device for mass transfer between two media separated by a membrane.

Ein belastungsarmer Blutstromübergang vom Anschlußbereich der Filtervorrichtung zu den Fasern des Hohlfaserbündels sowie eine gleichmäßige Ausnutzung der Fasern wird dadurch gewährleistet, daß die Membran in Form eines Hohlfaserbündels ausgeführt ist, dessen Faserhohlräume einen ersten Strömungsraum bilden, wobei wenigstens eine mit dem ersten Strömungsraum in Verbindung stehende Ein- oder Ausströmkammer zum Zu- oder Abfuhr eines Mediums in das oder aus dem Hohlfaserbündel vorgesehen ist, die an einen im wesentlichen kreis- oder teilkreisförmigen und in Richtung zu den Enden der Hohlfasern offen ausgeführten und mit einem Zu- oder Ablauf der Filtervorrichtung in Verbindung stehenden Kanal angrenzt, der näherungsweise zentrisch zu dem Hohlfaserbündel angeordnet ist und eine in Strömungsrichtung abnehmende Querschnittsfläche aufweist und der einen Außendurchmesser aufweist, der unter dem Durchmesser des Hohlfaserbündels liegt.A low-stress blood flow transition from the connection area of the filter device to the fibers of the hollow fiber bundle and an even utilization of the fibers is ensured in that the membrane in the form of a hollow fiber bundle is executed, the fiber cavities form a first flow space, wherein at least one inlet or Outflow chamber for supplying or removing a medium into or out of the hollow fiber bundle is provided, which is substantially circular or partially circular and open towards the ends of the hollow fibers and with a Inlet or outlet of the filter device in the adjacent channel adjoins which is arranged approximately centrally to the hollow fiber bundle and one in Has flow direction decreasing cross-sectional area and an outer diameter has, which is below the diameter of the hollow fiber bundle.

Die vorliegende Erfindung betrifft ferner eine Endkappe (30) für eine erfindungsgemäße Filtervorrichtung mit einer Ein- oder Ausströmkammer (10), die an einen im wesentlichen kreis- oder teilkreisförmigen Kanal (12) angrenzt, der in Richtung zu den Enden der Hohlfasern eines in einem mit der Endkappe (30) verbindbaren Filtervorrichtungsgehäuse (40) angeordneten Hohlfaserbündels offen ausgeführt ist und mit einem Zu- oder Ablauf (20) der Endkappe (30) in Verbindung steht, der näherungsweise zentrisch zu dem Hohlfaserbündel angeordnet ist und eine in Strömungsrichtung abnehmende Querschnittsfläche aufweist und der einen Außendurchmesser aufweist, der unter dem Innendurchmesser des das Hohlfaserbündel aufnehmenden Bereichs der Endkappe (30) liegt.

Figure 00000001
The present invention further relates to an end cap (30) for a filter device according to the invention with an inflow or outflow chamber (10) which adjoins a substantially circular or part-circular channel (12) which is one in one towards the ends of the hollow fibers with the end cap (30) connectable filter device housing (40) arranged hollow fiber bundle is open and is connected to an inlet or outlet (20) of the end cap (30), which is arranged approximately centrally to the hollow fiber bundle and has a decreasing cross-sectional area in the flow direction and which has an outer diameter which lies below the inner diameter of the region of the end cap (30) which receives the hollow fiber bundle.
